The AMS dating of pollen from syngenetic ice?wedge ice
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004Abstract The features of pollen occurrence in ice–wedge ice such as: size of pollen of tundra plants, incoming pollen into frost cracks together with melt water, dust and partially from host sediment and also clay envelopes around pollen grains caused the pretreatment methods of ice–wedge ice samples.

Involutions and Ice-Wedges in Devon
Nature, 1961RELICT periglacial phenomena have been recorded from south-west England for more than two hundred years. Reference has been made to head, clitter, rubble drift, loessic deposits and other manifestations of mechanical rock-weathering and ablation of debris under sub-arctic conditions1, to geomorphological features which resemble actively developing ...

The ecology of decaying ice wedges
2016En raison du changement climatique, le haut Arctique canadien connaît une des plus fortes augmentations de températures atmosphériques de la planète. Le pergélisol, sol qui demeure égale ou inférieure à 0 ° C pendant au moins deux années consécutives, est un phénomène cryospheric dont l'équilibre thermique fluctue en fonction des changements de ...

A fossil ice wedge at Perstorp, Skåne
Geologiska Föreningen i Stockholm Förhandlingar, 1977Abstract A fossil ice wedge is described. The wedge was about 0.5 m deep and almost as wide, even at the lower end. It cut through a bed of fine sand and coarse silt, which was overlain by sand and sandy gravel and underlain by sand and a sandy till.

Ice-Wedge Polygons of Northern Alaska
1982Ice-wedge polygons, commonly 5–30 m in diameter, are strikingly developed over the Arctic Coastal Plain of northern Alaska. Troughs over ice wedges that outline the polygons are a few centimeters to several meters wide. Centers of polygons are flat, high centered, or low centered in a continuum in which relief generally is several decimeters to a meter.
